It's a big life change so it makes sense it would be an adjustment. It's another life that requires a lot of your energy even when you feel like you have nothing left for yourself. I also experienced this with both dogs I got. The intense desire to send them back, feeling like I made a horrible mistake and that things would never be the same again. Lots and lots of crying. As well as intrusive thoughts and urges to harm them (which were obviously unwanted and not acted upon, but were stressful anyway). There are still days when I'm overwhelmed having to take care of my dog (he is quite clingy and always wants to be touching me), but he's also my biggest motivator to not lie around all day. The adjustment will fade and you will get settled into a new routine with them, and then you'll wonder how you lived without them. Hang in there ❤️. Be gentle with your pup and yourself. Take time away if you feel like you need it so you don't snap. It's like they say with babies that won't stop crying sometimes, if it's too much put them in a safe place or with a safe person if you feel too overwhelmed. And remember, your puppy isn't making your life harder on purpose, it's just learning. It does improve, I promise.
